***** and FALSE ADVERTISING

I ordered and paid for a particular plant online a week ago to be delivered today (sunday). The delivery guy arrived and handed me a completely different plant at a completely different price to the one I had ordered. I said it was not what I ordered and checked his sheet. The plant sent was marked as a substitute. I then went into my order and saw they had actually at point of order, charged me more than the pricing of the plant which was only stated in an email a recieved 2 days after I placed the order. I did not consent to this and I did not request a substitute of any kind. I called into costumer service to enquire why this had happened especially without my consent. To which they said at the time they probably had stock but not today... Which is why they charged me extra for the substitute 2 days later. Essentially I paid for an item I did not order because they had sold to available ones even after the money went out of my account on the day. There was no checking for consent on their behalf. They either did not have stock or they sold my order which was already paid for onto someone else. Both are *****. All the costumer service could do was say sorry and say they would contact me again in a few day to discuss a refund. Completely negating that the company had done what they had done... DO NOT buy from them online. They can and will access whatever funds they would like for products you did not purchase after falsely advertising items they do have in stock.
